Title: Solid electrolyte electrolytic cell
Inventor: INOUE YOSHIAKI
IPC: H01M8/12
Filed: 1992-07-15
Abstract: PURPOSE:To prevent the breakage of a substrate pipe due to thermal stress, prevent the leakage of the electricity flowing between electrodes to the substrate pipe, and improve the reliability of an electrolytic cell by forming the substrate pipe with a porous metal material arranged with an insulating layer on the fuel electrode side. CONSTITUTION:A substrate pipe 3 is made of a Ni-Cr heat-resistant allay having the porosity of about 30%, and an insulating layer 4 made of Al2O3 having the porosity of 20-30%, a fuel electrode 5 made of NiO having the porosity of 20-30%, a solid electrolyte 6 made of dense yttrialite stabilized ZrO2 having the porosity of 12%, and an air electrode 7 made of LaCoO3 having the porosity of 20-30% are formed on it in sequence by flame spraying. Since the substrate pipe 3 is made of a metal material having high heat conductivity, the temperature difference between the inner and outer faces is rarely generated at the time of power generation and flame spray, and its breakage due to thermal stress can be prevented because it is not fragile like a ceramic material. The electricity flowing from the fuel electrode 5 to the air electrode 7 is prevented from leaking through the substrate pipe 3 by the insulating layer 4.

Title: Traction control method
Inventor: OIKAWA HIROTAKA
IPC: B60T13/52
Filed: 1989-07-20
Abstract: PURPOSE:To improve the racing suppression effect of a wheel by a method wherein by actuating a brake booster before wheel speed information attains a threshold related to control of traction, a brake liquid pressure is accumulated, and when it attains the threshold, a wheel cylinder is immediately actuated. CONSTITUTION:During running of a vehicle, by a controller 19, a slip ratio S determined from a wheel speed and a false car speed is compared with preset thresholds S1 and S2, and in the case of S>S1, a vehicle is set to a control state of a mode 1, and brought into a normal drive state. In the case of S2<S>=S1, during acceleration in which the differential value of a wheel speed exceeds 0, a vehicle is set to a control state of a mode 2. After a power sources for a switching valve 5 and a control valve 9 is brought into an ON-state and a power source for a pressure release valve 12 is brought into an OFF-state, an atmospheric pressure is introduced in an actuating chamber 4 of a brake master 3, and the flow passage of a hydraulic system 8 is disconnected. This constitution causes accumulation of a brake liquid pressure for a master cylinder 6 in the hydraulic system 8 and exerts the brake liquid pressure on a wheel cylinder 7 during subsequent control of traction.

Title: Control device
Inventor: NAKAJIMA YOSHIHIRO
IPC: G03G15/00
Filed: 1987-07-27
Abstract: PURPOSE:To allow a control device to easily correspond to service interruption and noise by allowing a main control circuit to transmit/receive signals to/from an apparatus to be controlled through a connecting means and a sub-control circuit to control the apparatus to be controlled. CONSTITUTION:For instance, a main control circuit 10 including a CPU 11, a RAM 13 or the like is connected to the sub-control circuit 30 by a non-electric connecting means such as optical fibers 50-54. Since the main control circuit 100 is electrically separated from the sub-control circuit 30, the influence of noise invaded from a power supply line for the control 30 or the apparatus to be controlled and a switch or the like of the apparatus to be controlled is not exerted upon the main control circuit 10. Since power is supplied from an independent power supply such as a battery to the circuit 10, the circuit 10 can be continuously operated even if power failure is generated. Consequently, a complex counter plan for service interruption and noise is unnecessary.

Title: Motor speed control circuit
Inventor: MIZUMOTO MASAO
IPC: H02P27/06
Filed: 1990-07-16
Abstract: PURPOSE:To prevent flow of a through current into collector emitter route by delaying rise of a second output transistor through ON/OFF control of a control transistor based on a terminal voltage of a capacitor. CONSTITUTION:Since a capacitor C gradually charges according to the current of constant current source IG and a base current of a control transistor Q5 when the PWM signal falls to L from H, the control transistor Q5 gradually turns OFF, gradually turning ON the transistors Q2, Q4. Moreover, since an emitter voltage of a first output transistor Q1 is gradually lowered almost to the ground potential when the PWM signal falls to L from H, a base voltage of transistor Q1 drops following the emitter voltage of transistor Q1. Therefore, a time constant determined by a parasitic capacitance between the base and collector of the first output transistor Q1 and a shunt resistance R1 can be neglected and the through current is prevented to flow into the collector and emitter route of the first and second output transistors Q1, Q2.

Title: Switching system to spare line
Inventor: TANIGUCHI TAKAHIRO
IPC: H04B17/00
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a system for avoiding the cutoff of non-priority signal at the time of switching to a spare circuit which accompanies the quality deterioration of a current line in a transmission system of non-priority signal which uses a spare line of a ground microwave radio communication device. SOLUTION: Non-priority signal of a spare line is branched before a signal of a current line enters a spare line, and the signal is flowed to the current line where a line quality deteriorates. For instance, when the quality of a current line to which REG.1 is inputted deteriorates, a signal of the REG.1 is switched to a spare line and a signal of the spare line is flowed through the current line where the REG.1 flowed. With this, it is possible to transmit continuously non-priority signal even if its quality is bad to some extent. Similarly, a receiving side returns, a signal that is sent to the REG.1 by using the spare line and returns non-priority signal that is sent by the current line where the quality deteriorates to the spare line.
